My mother just informed me that there's a nude picture of child-me in a US State collection.
Here's how it happened: Mid-70's, my newly-divorced mother had accepted an invite to a private skinny-dipping party at a backyard pool, and had brought me along. Unbeknownst to her, one of the other guests was an amateur photographer. He was behind my mother and a male friend, when three-year-old me climbed out of the pool and walked toward her. Her friend has an apple in his hand, and quick as can be, the fellow takes a picture of the three of us. I'm in the centre of the picture, framed by the silhouetted forms of my mother and the man, the apple bright red in his hand. Gorgeous photo. It even won an award!
Unfortunately, my mother had no idea it had been taken until a friend of hers saw it on display in State museum, recognized me and called her. Mum was horrified. If it got out that she was going to skinny dipping parties, she could have lost her job. She might have even lost custody of me.
People made sure my father never found out about it, because no one was quite sure what he would have done.
And in the end, nothing was done because as my mum said, "There was nothing TO be done!" And the state purchased the photo, and now it's sitting in a collection somewhere.
All of which is to say, even in the era before digital photography and Facebook, we didn't always have control over our images.
